VALVE.

Specification of Letters Patent. Application filed January 2, 1909.

Serial No. 470,327.

To all whom it may concern:

Be it known that I, EMANUEL FISHER, J r., a citizen of the United States, residing at Providence, in the county of Providence and State ofRhode Island, have invented certain new and useful Improvements in Valves, of which the following is a specification.

My invention relates to rotary valves for use in connection with steam, gas, air, or any fluids or liquids, and has for its objects, simplicity, cheapness, and convenience of operation.

To these ends primarily invention consists in providing a structure wherein the operation of the rotary member shall sharpen or grind its seat rather than bruise or dull the same; and to afford in a single structure a capacity for quick, intermediate, and slow closure of the ports while the speed of the valve rotation remains uniform.

To the above ends, my invention consists in the novel construction and combination of the valve member and its seat hereinafter set forth in the specification and recited in the claims.

While my valve may be employed in engines and elsewhere, it is herein illustrated as a water valve.

In the accompanying drawings, which form a part of this specification, Figure l is a central vertical longitudinal section of a water valve casing and my novel valve and valve seat mounted therein, Fig. 2, a section on the line 10, w, of Fig. 1, Fig. 3, a longitudinal section of w w of Fig. 2, showing the parts in the position of quick closure, Fig. 4, a like section of the valve seat and valve, the valve being reversed end for end, to produce a slow closure,'Fig. 5, a similar section of the valve seat and valve in the position of intermediate closure, Figs. 6 and 7, sections on g y of Fig. 3 and z z of Fig. 5 respectively.

Like reference characters indicate like parts throughout the views.

The valve casing in conjunction with which my valve is herein sh'own comprises a body, A, provided with the usual top and bottom threaded pipe openings, B and C, and side openings, D'and E. Around the openings D and E are threaded rims, F and G, which are respectively removably engaged by the threaded heads or bonnets, H and I through the latter of which passes the the valve and seat on line' valve rod or stem, J, provided upon its outer end with a handle or wheel, K, and surrounded by a stufling box, L, threaded to the bonnet, I.

Mounted frictionally or otherwise in the casing openings, D and E, is a hollow, horizontally disposed, cylindrical valve seat or sleeve, M, provided with an opening or port, N, in its upper portion, and a serrated opening or port, 0, in its lower portion. This port, in other words, is a series of connected V-shaped openings, 0, extending longitudinally nearly across the seat, M.

The valve member which is rotatably mounted in the seat described is generally cylindrical in outline with a major portion of its body cut away forming annular end bearing portions or rings, Q, connected by a longitudinally disposed transversely curved bar, plate, or web, R, having a straight edge,

upon one margin, and provided upon its opposite margin with a row of serrations or V-shaped teeth, T, corresponding in dimensions and outline with the portions 0 of the port openings, 0.

The valve rod, J, is fixed to the end of the valve, in this instance to a diametrical or transverse cross bar, U, integral with one of the ring portions of the valve.

The operation of the valve is as follows: When the rod, J, is rotated, as shown in Fig. 3, the sides of the teeth and of the V- shaped portions of the port are parallel, assuring a quick closure of the port, 0. By reversing the direction of rotation of the valve member the straight edge, S, travels across the portions, 0, of the port, as shown in Fig. 5, and produces a somewhat slower cut off. To secure a still more prolonged cut off the bonnets or heads, H and -I, are unscrewed from their rims, F and G, the valve member withdrawn from its seat, and after reversal end for end, reinserted in the seat, M. The bonnet, I, is then screwed to the rim, F, and the bonnet, H, to the rim, G. This longitudinal reversal of the valve member relatively to the seat brings the apices of the teeth and of the V-shaped portions of the port into coincidence as the valve is rotated, as shown in Fig. 4, thus producing a still longer interval of closure.

What I claim is,

1. In a valve, the combination of a cylindrical seat provided with a port comprising a series of connected V-shaped openings,

Patented Dec. 19, 1911.

and a valve member rotatably mounted in the seat and adapted to cooperate with the openings.

2. In a valve, the combination of a cylindrical seat provided with a port comprising a series of connected V-shaped openings, and a valve member rotatably mounted in the seat provided with a row of serrations adapted to cooperate with the openings.

3. In a valve, the combination of a seat provided with a port comprising a series of connected V-shaped openings, and a valve member mounted upon the seat and adapted to cooperate with the openings.

4-. In a valve, the combination of a seat provided with a port comprising a series of connected V-shaped openings, and a valve member mounted upon the seat provided with a row of serrations adapted to cooperate with the openings.

In a valve, the combination of a cylindrical seat provided with a port comprising a series of connected V-shaped openings, and a valve member rotatably mounted in the seat and provided with a row of serrations comprising teeth corresponding in dimensions and outline with the V-shaped openings.

6. In a valve, the combination of a seat comprising V-shaped openings, and a valve member slidably mounted in the seat and adapted'to cooperate with the openings.

7. In a valve, the "combination of a seat provided with a port comprising V-shaped openings, and a cylindrical valve member slidably mounted in the seat.

8. In a valve, the combination of a cylindrical seat provided with a port comprising V-shaped openings, and a valve member rotatably mounted in the seat and adapted to cooperate with the openings.

9. In a valve, the combination of a cylindrical seat provided with a port comprising V-shaped openings, and a valve member rotatably mounted in the seat provided with serrations adapted to cooperate with the openings.

10. In a valve, the combination of a cylindrical seat provided with a port comprising a series of V-shaped openings, and a valve member rotatably mounted in the seat provided with a straight edge adapted to cooperate with the openings.

11.. In a valve, the combination of a cylindrical seat provided with a port comprising a series of V-shaped openings, and a valve member rotatably mounted in the seat provided with a st 'aight edge and provided with serrations, said straight edge and serrations being adapted to cooperate with the openings.

12. In a valve, the combination of a cylindrical seat provided with a port, and a valve member rotatably mounted in the seat provided with a straight edge and provided with serrations, said straightedge and serrations being adapted to cooperate with the port.

18. In a valve, the combination of a casing provided with side openings, a cylindrical valve seat mounted in the openings and provided with a port comprising V- shaped openings, a longitudinally slidable valve member rotatably mounted in the seat and provided with serrations adapted to cooperate with the openings, and removable members upon the casing around the openings inclosing the ends of the valve member.

14:. In a valve, the combination of a cylindrical seat provided with a port, a cylindrical valve partially cut away to form a longitudinally disposed web rotatably mounted in the seat, one margin of the web having a straight edge, and the opposite margin being provided with serrations, said straight edge and margin being adapted to cooperate with the port.

15. In a valve, the combination of a cylindrical seat provided with a port, a valve member rotatably mounted in the seat pro vided with a row of serrations adapted to cooperate with the port, and a valve spindle upon the valve member.

, In testimony whereof I have ailixed mv signature in presence of two witnesses.
